Sodium electricity: Solid-state sodium-sulfur batteries with energy density of 1000Wh/kg will be mass-produced in 2025

At the "Invest in China" Germany Special Presentation event hosted by the Ministry of Commerce of China, a German expert team has developed a complete set of high-performance and high-security solid-state sodium sulfur battery automatic continuous production process after nearly two years of research and development. This process can achieve an energy density of over 1000Wh/kg and a theoretical load capacity of up to 20000Wh/kg for the negative electrode. The process combines Germany's traditional advantages in high vacuum, fully automatic, nuclear physics, and magnetic levitation fields, and introduces new concepts such as ion printing and porous current collection, enabling the fully automatic continuous production of sodium sulfur batteries in a full vacuum environment with low cost and high production capacity. It is expected to launch equipment prototypes and battery samples by the end of 2023, have mass production capabilities by the end of 2025, and plan to collaborate with industrial funds and battery-related companies to invest in building factories in China.
